Guineans living in a dust storm, minority Shiites murdered in Pakistan, and more

This show is made up entirely of amateur images. We've seen time and time again how images captured by ordinary citizens then uploaded onto the Web can change history, or at least shift the balance of power. This week, we take a look back at some of those moments.

STORY 1: Pakistan

We begin today in Quetta, capital of Pakistan's Baluchistan province. The city is home to a large number of Hazaras, members of a Shiite minority who’ve long complained of discrimination across the border in Afghanistan. Now the Hazaras of Quetta say they’re threatened too, by a surge in activity by Wahabi extremist groups who don’t like their brand of Islam. Dozens of Quetta's Hazaras are killed every year in terrorist attacks.

STORY 2: Guinea-Conakry

Now to Guinea-Conakry in West Africa. The former French colony has rich natural resources in its forest region, especially gold and bauxite. That makes for a lot of trucks... bad news for inhabitants of the regional capital, like our Observer, Caleb Kolié.

STORY 3: World

Next up, a look at some of the images sent in this week by our Observers.

First off, a photograph taken on a flight from Italy to Tunisia, by Francesco Sperandeo. He was astonished to see two men bound and gagged on his plane. They were illegal immigrants being deported back to Tunisia, but Francesco couldn't understand why it was necessary to gag them with tape. He posted his pictures on Facebook, and they caused outrage in Italy. Prosecutors are now looking into the incident.

Now to Tunisia itself - Bourguiba Avenue in the capital Tunis, with our Observer Asma. During Tunisia's revolution, the avenue was a center of protest. We've often shown pictures of angry demonstrations, sometimes violence. But this time, it's different. This event was organised on Facebook. People were told to bring books out onto the avenue - and read them. This was a way of saying, the violence is over, it's time to look ahead to the future - and the future is about culture and education.

Now to Iran, with our Observer Kianouche Amiri. He tells us the capital Tehran has recently seen heavy rain, and widespread flooding - especially on the subway, which turned into an underwater river. Back on the surface, Kianouche tells us, young women took off their shoes to brave the floods... a daring act in Iran, where women are not allowed to bare their feet in public.

We finish today with Lieutenant Nguyen Manh Panh. He's the hero of the Vietnamese web this week, for going above and beyond the call of duty. When a bus driver refused to stop for a police check, Nguyen clung onto the windshield, at speeds of up to 50 km an hour. The driver eventually stopped, and was promptly arrested.
